G RAlN- HARVESTER.

SPECIFICATION forming part of Letters Patent No. 597,635, dated January18, 1898.

Application filed March 25, 1897.

To all whom it may concern.-

Be it known that 1, ROBERT IV. OOOMBS, of McOanna, in the county ofGrand Forks and State of North Dakota, have inventedcertain new anduseful Improvements in Grain-I-Iarvesters; and I do hereby declare thefollow ing to be a full, clear, and exact description of theinvention,-such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to a new and useful attachment forharvesting-machines and is intended to be used in connection with theaprons thereof to prevent the grain after having been cut from cloggingor otherwise becoming entangled therewith, the object being to provide adevice of this character which shall be simple and inexpensive inconstruction, which can be readily applied to the harvesters new in use,and which is particularly well adapted for use when harvesting flax orother products having a tendency to stick to the apron.

, My invention comprises certain novel features of construction andarrangement of parts whereby the above and other imporrant advantagesare gained, as will be hereinafter described, and specifically definedin the appended claim.

In the accompanying drawings, Figure 1 represents a detail perspectiveview of a portion of a harvesting-machine having my invention appliedthereto. Fig. 2 is a central longitudinal section of the same,lookin gfrom the opposite side. Fig. 3 is a detail perspective view of myinvention detached, and Fig. 4 is a detail View of a modified form of myinvention.

Similar reference-numerals indicate corresponding parts in all thefigures of the drawings.

1 represents the platform, 2 the apron, 3 the cutter-bar, and 4 theelevator, of an ordi nary harvesting-machine, and as these may be of anyordinary or known construction no detailed description thereof is deemednecessary,

My improved attachment is arranged immediately behind the cuttenbar andadjacent to the edge of the apron, and consists of a bar of steel oriron 5, having end supports or Serial-1N0. 629,142. (No model.)

lugs 6 formed thereon, the latter being provided with openings for bolts7, which serve to fasten the bar to the frame of the platform. The bar 5is so arranged that its upper edge will lie about upon alevel with theslats 3 of the apron, and one end of the bar is arranged to extendbeyond the outer end of the apron, while the other end hasan extensionS,which is turned or twisted at the point 8, so that it may lie fiatupon the slats of the apron 9 of the elevator i, which latter is of anyordinary or usual construction.

The grain or other product after having been cut by the knife falls overthe bar 5 onto the apron 2, the ends of the stocks resting upon the edgeof the bar, while the remaining portion thereof will lie upon the apronand between the slats, by which means they are conveyed to theelevator-aprons. The bar 5 will thus relieve the apron of a greatportion of the weight of the grain and serves to keep one end thereofraised slightly above the apron, and by reason of the bar being arrangedto lie close to the edge of the apron all possibility of the grainbecoming entangled therewith is positively prevented and its delivery tothe elevator-aprons greatly facilitated.

The extension 8 of the bar 5 serves to relieve the canvas of theelevator over which it extends from a heavy strain and ata point where adrag is liable to occur, and it is to be understood that the attachmentheretofore set forth is intended especially for use on a harvester forhandling and elevating flax, which has a tendency to pack and gather atcertain points on the apron and elevator and impede the proper operationof said parts.

In practice I may bend the upper edge of the bar 5, so as to form aflange 5 at right angles thereto, under which flange apron 2 and slats 3will travel, and this construction will aiford greater security againstthe entanglement of the grain with the apron. I reserve the right tomake this change and otherwise alter the parts herein described in suchmanner as may be considered to lie within the spirit and scope of myinvention.

It will thus be seen that my invention provides in a simple andeffective manneran attachment for harvesters which is particularly ICOwell adapted for the purpose for which it is intended, which is noteasily gotten out of order, and which can be readily applied to theharvesting-machines at present in use, it being obvious that by its usethe heavy strain put upon the apron is very materially reduced and thewear and tear of the canvas mate- I rially lessened.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

An attachment for a harvesting-machine, comprising a bar arrangedadjacent to the platform-apron, and provided with lugs or ROBERT XV.COOMBS Witnesses:
